jacoco:report-aggregate 要么覆盖范围较浅，要么根本没有覆盖

Dav*_*arr 6 maven jacoco jacoco-maven-plugin

我有一个大型的多模块 Maven 构建，目前混合了 PowerMock 和 Mockito 测试（很快将所有 PowerMock 测试移至 Mockito）。父 pom 中的默认 jacoco-maven-plugin 配置用于“离线”检测，但带有 Mockito 测试的模块正在使用在线检测。我相信模块中的每个 jacoco.exec 文件都已正确构建。

其中一个子模块称为“jacoco-aggregate”，只是尝试使用“合并”和“报告聚合”目标。我使用“合并”是因为我正在与 SonarQube 集成，并且我们使用的版本仅允许单个执行文件。从输出中我可以看到，“合并”目标似乎运行正常。

“报告汇总”目标似乎有问题。目前它根本没有产生任何报道。显示的表是空的。

以下是我在 jacoco 子模块本身中构建时得到的当前输出：

请注意，我指定了其他 jacoco 目标的执行，因为这些目标是在父 pom 中指定的，预计将由普通代码模块使用。将“阶段”设置为“无”是有效禁用该目标的一种方法（并不是说它特别干净）。

在我在“jacoco-aggregate”中手动运行构建之前，我查看了其他模块中引用的几个“jacoco.exec”文件，它们都存在并且非空。

Answer 1

God*_*din 2

第一个-似乎是您merge之后做的report-aggregate，所以最后一个看不到jacoco.exec。

另请注意，report-aggregate调查反应堆项目，即如果您有

root
  \child_1
  \child_2

那么在执行反应堆期间mvn ...将root包含所有 3 个，而在执行cd child_2 && mvn ...反应堆期间将仅包含child_2.
